DeepFaceLab is a prominent software tool for creating deepfakes, used by over 95% of deepfake videos. It offers various features including face replacement, de-aging, head replacement, and lip manipulation. The software requires users to invest time in learning its workflow and may necessitate skills in video editing tools like Adobe After Effects or Davinci Resolve. The project is open-source, available under the GPL-3.0 license, and supported by a large community contributing guides, facesets, and pretrained models.
